Hello everyone
This is my first post in this forum and hope you will be able to help me?
I have recently bought Sony 70-300 G from Jessops and as I was examining it back home I noticed that there was a rattling sound but only in certain shakes. So i took it back and got another one but still the same issue.

I am not sure whether its a normal sound (caused by the aperture's blade hitting each other) or its a second lens with a similar problem.

I have checked my other lenses ( Sony 18-70, Minolta 70-210, Sony 5014) but no similar sound.

Anyone has got an idea? especially if you already own the Sony 70-300 G.

There's a couple of 70-300mm G users around here, so they could tell you whether the sound is a problem or not. Aperture blades aren't supposed to make noise though, so I'm guessing it's a problem. You might also want to contact Sony about it.

Well my first lens was bought from Jessops Brighton. When the guy brought it out the seal seem to be old, I have asked if it was brand new and he assured me it was. Took it back home and that was when i heard that rattling noise. The second lens was ordered from Jessops online and arrived from Nottingham. The seal was in brand new condition and I was 100% sure that it was brand new but I could still hear the same rattling noise.

I am going to contact Jessops tomorrow as well as Sony and I guess I will be replacing it again.

Sony's the first company to contact now. Ask them If they've gotten similar complaints before and whether it's a problem most lenses have. Cause if most 70-300mm make that noise, you might need a lot of replacements.

I am worried that I am causing a bit of confusion. When one shakes a lens of course one will hear some noise but the rattling that I am hearing is like a tiny piece of metal stuck inside and keeps on hitting the surfaces inside as you shake the lens. I am worried that its a screw out of its place. (My cheap kit lens does not make that noise at all!!!)

Sony confirmed this morning that this rattling noise is a fault and they have assured me that it shouldn t be happening. I phoned Jessops and in a rude way asked me to return it which I will be doing on Saturday morning. I m starting to think that they have got a promotion on this lens because they have only got faulty ones. But again I could be third time lucky ;D

Quick update...
I went back to Jessops to return the lens. Did not get a nice reception as if I ve done something wrong. The guy there was trying to convince me that there was nothing wrong with the lens so he went and shook all the sony display lenses but with no luck then he moved on to the canon ones (made me laugh even though i was getting upset). Cut a long story short, I have returned the lens and ended up buying another lens on my list from Park Cameras. Now I own my first and hopefully not last Carl Zeiss Lens 16-80
